Wind Tunnel Test of Shielded Flat Plant Wind Rotor

Abstract

A rectangular flat plate rotor was tested inside a wind tunnel. The plate was half shielded by semi - cylindrical cover so that the wind strikes one half of the plate. The power coefficient and output torque were found experimentally for value of the tip speed ratio ranging from zero, when the output is sufficient to stop the turbine, to the maximum free running value when the output torque is zero.
